Peter, I'm not aware of the Prototipo ever being made in a size other than 350mm, although there was a wooden rim version that was 370mm. Momo has never stopped making the Prototipo. They currently produce it in a few different spoke color and leather variations. The only other change they've made, over the years, is to slightly enlarge the holes in the spokes. If they would be willing to do a run of 320mm Prototipo's, what is their minimum quantity requirement?
Would Momo be willing to re-make the correct Pantera hub adapter with the DeTomaso horn button? The part # is/was 4908 but it hasn't been available since the '80's. In the '90's, Momo told me the minimum quantity would be 100.
